I have just came to Area 51 and my first action was to upvote some questions on a new proposal. The upvote went ok, I have spent all my votes, but then I have decided that I do not want to upvote one of the questions I have upvoted, and that I want to upvote instead, another question, because it is more relevant to me.

When I have tried to downvote, it said that I require 150 reputation to vote. So seems like the proposal upvoting has some special mechanism that can override the usual voting one, and that's not the case with downvoting.

Casting a downvote is different from un-casting an upvote. If you want to change your vote, you need to first "unvote", and then move the vote to another question. Click the upvote arrow beside the question you upvoted to un-upvote it.
